WHEEL GARDEN-HOE.

Specification of Letters Patent.

Application filed May 25, 1908.

Patented Aug. 23, 1910.

Serial No. 434,969.

To all whom it may concern:

Be it known that I, THoMAs HAZEN HUM- PHREYS, a citizen of the UnitedStates, residing at Kissee Hills, in the county of Taney and State ofMissouri, have invented a new and useful Wheel GardenI-Ioe, of which thefollowing is a specification.

This invention relates to machines for use in garden cultivation, andhas for an object to provide a hoe adapted to be mechanically operatedupon movement of the machine, and to provide a driven crank shaft gearedwith elements of the machine so that a continuous rotary motion isimparted to said crank shaft in order that suflicient power can betransmitted to the hoe to provide for its perfect operation.

A further object of my invention is to provide a machine of the abovedescribed character that can be put upon the market ata relatively lowcost and to construct the machine in a compact manner so that it may bemanually propelled through a garden or field with but little exertion onthe part of its operator.

Other objects and advantages will be apparent as the nature of theinvention is better set forth, and it will be understood that changeswithin the scope of the claim may be resorted to without departing fromthe spirit of the invention.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a side view of the machine. Fig. 2 is a top plan view.

Referring now more particularly to the drawing, there is shown a frame Acomprising longitudinally disposed parallel spaced beams or bars 10provided with handles 19. of suitable form so that they can be engagedby the hands of an operator in order that the machine can be manuallypropelled through a field or garden. The bars or beams 10 are providedwith bearing boxes 11 in which is mounted a shaft 11 The shaft 11 hasmounted thereon a drive wheel 1 adapted to support the frame, and thesaid wheel is located or disposed between the said beams or bars 10, andas clearly indicated the drive wheel has secured thereto in any suitablemanner a gear wheel 2 which in the present instance is slightly less indiameter than the diameter of the drive wheel, but it will of course beunderstood that I do not rely particularly upon the exact size of thegear wheel 2, as it is obvious that it may be of any suitable size toproduce the desired results.

Adjacent to the front ends of the beams or bars 10, I mount thereonjournal boxes 13 which receive a crank shaft 11 provided for a purposeto be hereinafter set forth. An oscillatory arm 9 is mounted upon one ofthe beams or bars 10 and is provided with a flattened portion 9 in whichis formed a plurality of adjusting passages 9 A hoe 10 is carried by thedownwardly extending portion 8 of an element 8 and as clearly indicated,said element is provided with a bearing portion 8 engaged with the crankportion 6 of the shaft 11 From the bearing 8 the element 8 is extendedrearwardly and it is loosely engaged with the portion 9 of the arm 9 bymeans of a removable bolt 8 passed through one of the passages 9 Byproviding the passages 9 and the removable bolt 8, I effectively providesimple and novel means for adjusting the stroke of the hoe-carryingelement 8. The crank shaft has secured thereto outwardly of one of thebeams or bars 10, a pinion 5 in mesh with a gear wheel 4 mounted upon astub axle 4? which latter is journaled in a bearing upon one of thebeams or bars 10. The shaft 4 carries a pinion 3 in mesh with the gear 2so that when the machine is in operation, power supplied to the shaft 4*will be transmitted to the crank shaft 11 to consequently impart to theelement 8 an oscillatory movement as will be readily appreciated. Theshaft 43 is journaled in a suitable bearing box 14: upon the frame A. Inorder to provide a more perfect operation of the shaft 11', I mountthereon a fly wheel 7.

The construction of the machine as herein set forth and described issimple, its parts being arranged in a compact manner, and theconstruction is such that the machine may be manually propelled througha garden or field. Upon movement of the machine in a forward direction,power will be transmitted from the main drive wheel to the crank shaftto consequently impart to the hoe-carrying element an oscillatorymovement.
